Abstract: The invention relates to an active noise reduction system for the interior of motor vehicles and other means of transport, having noise sensors (microphones) (1a, 1b), loudspeakers (2a, 2b) and at least one control device (3) which contains the output signal of the noise sensors as an actual variable and emits control signals which act on the loudspeakers, the noise-reduced spatial area being under the influence of two or more differently acting subsystems. In these subsystems, the spatial distance between loudspeaker and microphone is relatively small (1b, 2b) (''near field'') or large (1a, 2a) (''far field''). The frequencies for the near field which are to be processed by the control device (3) are above a characteristic threshold frequency fg and those for the far field are below said threshold frequency. The two subsystems are complementary in their mode of operation in accordance with the vehicle conditions. <IMAGE>

Abstract: In this method, the data are transmitted between a data memory (2) and a read/write device (7) via an interface with a wireless signal link. The interface is formed by disposing an optical scanning head (4), which is connected to the read/write device (7), physically adjacent to an optical transmission head (3) which is connected to the data memory (2) to produce an optical signal path. The electric power required to read out data on the side of the data memory (2) is generated in a transmitter (6), under the control of the read/write device (7), as a high-frequency signal and is transmitted via an induction coil (4.1) disposed on the optical scanning head (4) to an induction coil (3.1) disposed on the optical transmission head (3). The feed voltage for the operation of the interface of the data memory (2) is generated from the rectified high-frequency signal. <IMAGE>

IPC: H01L21/8247
Filed: 1991-06-15
Abstract: An array (250) of asymmetric electrically programmable, read only memory (EPROM) cells is formed in a P- semiconductor substrate (252). The EPROM cells (254) are virtual ground cells, in that there are no fixed connections in the array to ground potential. Parallel bit lines (BL), comprising N+ substrate regions (194), form the drain and source regions of parallel columns of MOS transistor devices. Each EPROM cell has a floating gate (256) formed on a first polysilicon layer, and a control gate (258) formed on a second polysilicon layer. Each bit line has two lateral edge regions. An N- implant region (280) overlaps one lateral edge region of each bit line, thereby forming a graduated PN junction between the drain and channel of each MOS transistor device. This substantially prevents hot electron generation by the drain and enables one cell to be programmed without programming of its nearest neighboring cell. A second P- implant region (282) overlaps the other lateral edge region of each bit line, forming a sharp PN junction between the source and channel of each adjacent MOS transistor device, thereby enhancing hot electron generation, which makes the programming of cells more efficient.

Abstract: Light beams having two different power levels are radiated on a magneto-optical medium having a recording layer (1) and a bias layer (2) magnetostatically coupled to the recording layer (1), thereby recording and erasing information. Upon radiation of a high level beam, a beam irradiated portion of the recording layer (1) is heated to reach a magnetization reversal temperature, and the direction of magnetization of the irradiated portion follows a direction of a leakage field generated by a magnetization distribution formed by heating of the bias layer (2). Upon radiation of a low level beam, a beam irradiated portion of the recording layer (1) is heated to reach a magnetization reversal temperature to cause the bias layer (2) to generate a leakage field having a magnitude smaller than that upon radiation of the high level beam. In this case, the direction of magnetization of the recording layer (1) is opposite to that of the leakage field obtained upon radiation of the high level beam. The directions of magnetization of the bias layer (2) are kept unchanged before and after the radiation of the high level beam and before and after the radiation of the low level beam.

Abstract: A method for the solubilization and naturation of somatotropin from refractile bodies produced by r-DNA technology wherein the refractile bodies are dissolved in an aqueous solution comprising a chaotropic agent such as urea or guanidine hydrochloride and a soluble surfactant such as sodium dodecylsulfate. The solubilized protein is exposed to mild oxidation for a time sufficient to allow the protein to form disulfide bonds and refold to its native conformation. The presence of the surfactant suppresses the formation of somatotropin dimers and aggregates and results in higher yields of the desirable monomeric form of the protein.

Abstract: 2.1. Optically active molecules and biomolecules such as peptides, amino acids and nucleic acids are sensitive to increased temperatures, extreme pH and/or long reaction times. In chemical syntheses these molecules therefore easily undergo racemisation or denaturisation. Using the novel process, the hydrolysis, ammonolysis or transesterification of acid derivatives or cleavage of polymer-bound molecules is to be possible under mild reaction conditions. 2.2. The transesterification, hydrolysis or removal of polymer-bound molecules, such as, for example, in the Merrifield synthesis, is carried out by the combined use of an amidine base and a metal compound in the presence of an alcohol or water. In the hydrolysis of amino acid or peptide esters, the cleavage takes place even only using lithium hydroxide under mild conditions. The use of an amidine base, in particular DBU or DBN, in combination with the metal salt accelerates the reaction so greatly that even sensitive acid derivatives can be reacted under mild conditions. 2.3. Preparation of complex esters, mild removal of peptides from the support, mild hydrolysis of amides or esters.

Abstract: Breathable barrier fabrics are made by sizing a substrate, made of bonded fibers forming void spaces therein, with a film-forming material that fills the voids of the substrate to form a solid film between the fibers. The resulting non-porous breathable material provides a high strength fabric which is permeable to water vapor, such as body moisture, but impermeable to air and aqueous liquids. The non-porous breathable barrier fabric acts as a barrier against wind, dust or other airborne contaminants, e.g. bacteria, viruses, pesticides, etc., as well as against aqueous liquids such as blood. Alternatively, porous barrier fabrics can be made by incorporating air into the film-forming filler material to obtain greater comfort at lowered barrier qualities. The barrier fabrics of the invention are suitable for industrial, hospital and other protective covering uses.

Abstract: In a method and system for processing image data from a document (12) a compressed binarized version of the image data is produced for transmission to or use by subsequent users. Processing of the image data is done in parallel after the scanning of the document (12) is started but before the entire document (12) is scanned. A splitter (32) is used to divide a scan line of image data produced by an imager at the scan line into a plurality of channels, with each channel having at least one overlap area of pixels and with the overlap areas of pixels being used to avoid errors between channels. Thresholding and compression are performed by each one of the channels in parallel. The compression is performed in a direction which is perpendicular to the direction of scanning and conforms to a standard compression algorithm.

A sealant member (20) and radially spaced clasps (19) are located around the sealed openings (51) and strain relief members so that the connector may be removably twist-locked onto a bulkhead without disturbing the sealed wires. 
     There is also provided a method for achieving the sealed pass-through of electrical conductors.
